Got "would"?
Americans with mullets.
(White people with dreds would be on the list, but they tend to sell really good dope, so on that count they actually contribute to humanity.)
Seriously--as a benevolent dictator charged with the cold and dispassionate stewardship of the human species, I would tend to eliminate anyone who attempted to bend the rules toward a more restricted benefit. I have no problem with standards being forced wide open on behalf of the people, but my response to people trying to twist laws in order to profit while openly hurting other people is obscene. Therefore, the insurance industry has to go. As a benevolent dictator, my state would be obliged to the people's benefit, therefore lawyers become largely unnecessary. Set a quota and dump the rest in the ocean. Serial killers, paedophiles, and other deviant criminals would be kept alive in order to study them. There would be no door-to-door salesmen or telemarketers to kill; nobody should be forced to opt for that manner of making a living.
Oh, and whoever's responsible for turning a spoon-holder into a piece of hanging wall art. That freak and their entire gene pool to the fourth and fifth valences.
Does anyone think I'm joking? Remember that liberals are liberal because God help the world if we ever go conservative. Take the American neocons, for instance. Disgruntled liberals, or so says the grandfather of neoconservatism. Or father. Or ... I don't know, it was some dumb, affectionate title.
I mean, when an ideology so fraught with artists wants to kill, expect it to kill artfully. Which means jaw-droppingly, morbidly-beautifully, insanely, hugely impressively. National Geographic, in 1996 or '97, noted that a theoretical voluntary restriction to one child per couple, by the effect of requiring two parents for only one offspring, would reduce the world population to something like 3.5 billion by 2050. I could accomplish that decrease in six days, taking the seventh for my rest--well, that is, if I was the benevolent master of all humanity.
